VERT, or GREEN RITE, in forest law, any thing that grows and bears a green leaf within the forest, that may cover a deer. This is divided into over-vert and nether vert ; over-vert is the great woods which, in law-books, are usually called hault bois ; nether-vert is the underwoods, otherwise called sub-bois. We sometimes also meet with special vert, which de notes all trees growing in the king's woods within the forest ; and those which "April 26th, in the evening, at nine o'clock, true time, I succeeded in effect ing the measurement of Vesta, with the same power of 288, by means of the thirteen feet reflector, with which that of Ceres, Pallas, and Juno, had been made ; and when viewed by this reflector, it also appeared exactly in the same manner. Of several illuminated' discs, of 2.0 to 0.5 decimal lines, which I had before made use of for measuring the satellites of Sation and Jupiter, the smallest disc only of 0.5 lines could be used for this Purpose ; by it the rounded nucleus of the planet Vesta, when the disc was at the distance of 611.0 lines from the eye, appeared almost of the same size, and I must even estimate its diameter as one sixth smaller. If, therefore, we attend, not to the full magnitude of the projec tion, but the estimation just mentioned, it follows, by calculation, that the appa rent diameter of the planet Vesta is only 0.483 seconds, and consequently, only
half of what I have found to be the appa rent diameter of the finirth satellite of Saturn. This extraordinary smallness, with such an intense, radiant, and un steady light of a fixed star, is the more remarkable, as, according to the preli minary calculations of Dr. Gauss, there can be no doubt that this planet is found in the same region between Mars and Ju piter, in which Ceres, Pallas, and Juno, perform their revolutions round the sun; that, in close union with them, it has the same cosmological origin ; and that, as a planet of such smallness and of so very intense light, it is comparatively near to the earth. This remarkable circumstance will no doubt be productive of important cosmological observations, as soon as the elements of the new planet have been sufficiently determined, and its distance from the earth ascertained by calcula tion." Much of what is said of Vesta is appli cable to the other small planetary bodies referred to in this article.
